So I understand that the SL30 connects the TX lead to the dynon100. As I'm looking at my SL30 install manual pg.20 fig.9. Is the Tx line that is being refered to the lead from pin 5 on the SL30 ? Does anyone know for sure if that's right?
From looking at the SL30 and D-100 manual, you are correct. the SL30 pin 5 is the serial data TX. This should end up at the Dynon Serial receive pin 22.
Look at page 3-5 in the dynon manual, second section from the bottom.
